Building challenges are always, well, challenges. Part of me loves the fun of them, and the unconventional techniques they force me to use when building. But, another part of me wonders how much better the MOC could be if I wasn't limited in parts. Which do you prefer - building challenges, or just regular MOCs? If you missed it, check out my Custom Ninjago Crystalized Mechs here, where I was not limited in the parts I used: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-_injmFxSj2E.html
The Col and Kai combo look like what the Land Bounty could have been. Jay's bike is awesome and now I think if he had a special type of dragon, I think he'd have a twin headed one. These all look great and maybe one day you could use more pieces on this and make it into an even better vision of what you'd like.
All of them are extraordinary but personally my favorite builds are the Jay bike and the Kai monster truck like build. The efforts definitely payed off.
Reminds me of the project I am working on. 6in1 combiner(Kai Zane Cole Jay Lloyd and Nya) but instead of them all combining into a standard vehicle, I am going Voltron/Megazord style.
I think a better Idea would be to have the cole vehicle be at the front, and leave the Jay bike in the middle while having some of the kay vehicle cover the back wheel of the bike. Or even have it like the ultra stealth raider with the big bike in the middle, smaller vehicles for kai and cole on the sides and jet on top more to the back. But all in all great job.
if you ever try and redo this set...try and take inspiration from the Worriz Combat Lair from Chima...it had an interesting way to incorporate a motorcycle, that could change into just a portion with two wheels, and I feel it could fit well for Cole's vehicle
